You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 201 km south and 194 km east. Mt. Rainier is locat

elixir [45]

Answer:

The answer is "0.0846276476".

Step-by-step explanation:

Let all the origin(0,0) of JBLM be

Let the y-axis be north along with the vector j unit.

But along the + ve x-axis is east, and all along with the vector unit i.

And at (194,-201) that undisclosed position is

Mt. Ris (56,-40) at

Let the moment it gets close to the Mt. rainier bet.

Oh, then,

If we know, the parallel to the direction from the point was its nearest one to a path to a point,

Calculating slope:

$\to m=\frac{y_2-y_1}{x_2-x_1}\\$

points: (0,0) and (194,-201)

$\to m=\frac{-201 -0 }{194-0}\\\\\to m=\frac{-201}{194}\\\\\to m=-1.03$

equation of the line:

$\to y= mx+c\\\\\to y= -1.03\ x+c$

when the slope is perpendicular= $-\frac{1}{m}$

$= - \frac{1}{ -1.03}\\\\= \frac{1}{ 1.03}\\\\= 0.97$

perpendicular equation:

$\to y-(-40)=0.97 \times (x-56) \\\\\to y+40=0.97 \times (x-56) \\\\$

Going to solve both of the equations to have the intersection point,

We get to the intersect level in order to be at

(47.16,-48.5748)

so the distance from origin:

$= \sqrt{(47.16^2+48.5748^2)}\\\\= \sqrt{2224.0656 + 2359.5112}\\\\=\sqrt{4583.5768}\\\\=67.7021181$

$\to time =\frac{distance }{speed}$

$= \frac{67.7021181}{800}\\\\= 0.0846276476$

Suppose you want to throw a party. you have $214 to spend. so far you have purchased 5 decorations that each cost d dollars. whi

Harrizon [31]

Answer: 214 - 5d

Which of the following real-world scenarios could be represented by the algebraic expression 7.65 - 2p? Select all that apply.

Answers:

1) You buy 2 equally priced party favors, spending from your $7.65 gift card.

4) you give Tim twice the amount of face paint he had from your supply of 7.65 ounces.

You decide to order pizzas for your party. A large pizza is cut into 12 slices. If each pizza is shared evenly among G guests, which expression represents the number of slices that each guest will eat?

Answer: 12/g

(these are the rest of the answers for the rest of the 7 slides of "Writing expression" assignment on e2020

4th: $25 dollars is the constant team so the cost for h hours is 15h and the correct expression is 15h+25 and 15(h+25) would be interpreted as adding 25 hours to the number of hours rented, and then multiplying by 15.

5th: m + 2m - s

6th: No it's not true. Each table began with x/8 balloons. If two pop then you will not be able to distribute it equally among 8 tables. There are x/8 - 2 balloons left. Not all tables will be equal.

7th: n - (1/4)n - 15

8th: 12n/r

9th: (x+3)/5

10th: (3r)/2 is what the second DJ had. 3 times as many songs as 3r and half as many is translated as division to 2 so half as many is translated as multiplication by 1/2. So therefore, the second DJ had (3r)/2 songs.

I need help on this please help!

Licemer1 [7]

Answer:

(b)0.56

Step-by-step explanation:

(a)

P(Ben Pass) =0.8

Therefore: P(Ben fails)=1-0.8 =0.2

P(Tom Pass) =0.7

Therefore: P(Tom fails)=1-0.7 =0.3

See attached for the completed tree diagram

(b)Probability that both will pass

P(both will pass)=P(Ben pass and Tom pass)

=P(Ben pass) X P(Tom pass)

=0.8 X 0.7

=0.56

(c)The probability that only one of them will pass

Since either Tom or Ben can pass, we have:

P(only one of them will pass)

=P(Ben pass and Tom fails OR Ben Fails and Tom Pass)

=P(Ben pass and Tom fails)+P(Ben Fails and Tom Pass)

=(0.8 X 0.3) + (0.2 X 0.7)

=0.24 + 0.14

=0.38
